✦ Synopsis


Coplanar wa¨eguides nowadays are successfully used to feed printed antennas. This technique is ¨ery interesting for antenna arrays. Howe¨er, the complete system in¨ol¨es the association of se¨eral microwa¨e functions, essentially power di¨isions and phase shifts, which are easier to implement in microstrip technology than in CPW technology. In order to match these requirements, this paper presents some compact and easy to realize microstriprCPW transitions.
